certain new and useful- Improvements in Stora e-Battery Circuit Controllers and T I of winch the following is a speciilCtPtlOl];

The object of my invention is to produce a. neat a'ndreadily installed instrmnent adaptin be placed in the circuit between a storge battery and charging generator by means of which the current-productive value of either the generator or storage battery may be readily learned and by means of which the generator may be connected to the storage battery in such manner as to permit charging of the storage battery from the generator without interfering with the service duty being exacted from the storage battery.

The accompanying drawings illustrate my invention Figure 1 is a perspective view of the instrument; Fig. 2 a front elevation (full size) with the front plate of the switch. box removed; and Fig. 3 a diagram of the wiring necessary for installation of the instrmnent.

In the drawings, 10 indicates the main body of the instrument provided with a cylindrical upper portion 11 within which is mounted a current meter 12 of any desirable and proper construction, the meter preferably being :1 volt meter. Carried by the main body 10, and insulated therefrom, is a switch block 18 which may conveniently be formed of an insulating material such ebonite, in which are formed three pockets 1 1, 15 and 16, and extending transversely through block 13 crossing the upper ends of ,the three pockets, is a passage or bore 17 gwithin which is slidably; mounted a switch pin 18 said pin 18 having metallic ends 19 and 20 which are electrically connected through a central 7 insulating portion 21.

Mounted in pocket 14 is a spring terminal adapted to engage the metallic end 19 of the switch pin, and mounted in. pocket 16 is a spring terminal 2 which is adapted to en! gage the'metallic end 20 of the switch pin, while mounted in the central pocket 15 is a terminal comprising a pair of spring contact fingers one of which is adu to en the end 19 ct si Specification of Letters HOMER N. lVlCO'ISIINGrIElR, OF PENBLEIGN, INDIANA, ASSIGNQR TG MOTSINGER DEVICE INDIANA, A SOPIPGE-ATEGN OF INDIANA.

AND

it is pushed inavard while the other is adapt ed to engage the end 20 of the switch pin when it is pushed in.

lslounted upon the main body 10 in convenient and accessible position. are three binding posts 31.. 32 and 33. Post 31 connee-ted by a wire 3-1 with terminal post.

32- is connected by a wire 35 with the positive fire of the current meter 12, and post is connected by a wire 36 with terminal A wire 31" connects terminal 25 with "ire side of the current meter. .nistailing this instrument post 31 is conncc ed by a wire %1 with the negative.

the positive side of a torage battery 12; side ot the storage battery is connected by a wire with the positive side of a generator i i; the negative side of the generator is connected by a wire i with post and postis connected by a wire 46 with the positive line between the storage battery and generator, this connection being made at any convenient point. Service lines 51 and 52 lead from the storage battery terminals.

The operation is as follows c-By ushing the switch pin to the right (F 2) so that the end 19 connects terminal 23 and terminal 25 a circuit is established as follows; starting from the positive pole of the storage battery 42,, through wires 43 and d6, binding post 32, wire 35, instrument 12, wire 37, terminal 25, switch pin portion 19, terminal 23, wire 3%, binding post 31 and wire 41 to the negative side of the battery thus giving a reading on the current meter from the storage battery without interfering with delivery of the storage battery to the service lines 51 52. By pushing the switch pin to the left (Fig. the insulating portion. of the switch pin comes beneath terminal 23 and the metallic portion 20 connects terminals 24 and 25 thus establishing the follow ing circuit :--from the positive side of generator 44: through wires 18 and 46 to post 32, wire-35 to the current meter, wire 37,

pin portion 19 and 2G and ins the following circuit is thereupon established:from' the positive side or the generator to the positive side'of the storage battery through wire 43, through the storage battery and wire 41 to binding post 31, wire 34, terminal 23, switch pin portions 19 and 20, terminal 24, wire 36 post 33 and wire 4C5 to the negative side of the generator-whereupon the generator will serve to recharge the storage battery and also serve the service lines 51 and 52. By this means the operator may readily determine whether it is advisable or necessary to connect the generator with the storage battery for recharging.

The instrument is compactly and conveniently arranged ready for easy installation.

I claim as my invention:

1. The combination of a generator, a storage battery, a meter circuit, a meter connected in said meter circuit, a switch block comprising three terminals, a switch pin formed to connect said terminals in pairs, and connections between the generator and one of said terminals, between the storage battery and another of said terminals, between the meter and the other of said terminals, and between the met-er and the storage battery and generator, for the purpose described.

2. A- switch-meter instrument comprising a main body carrying the following parts,'

In witness whereof, I, have hereunto set my hand and seal. at Indianapolis, Indiana, this twenty-seventhday of January, A. D. one thousand nine hundred and nine.
